Harbor Care

Harbor Care is a nonprofit substance use treatment facility located at 45 High Street in Nashua, New Hampshire, serving individuals facing addiction and co-occurring mental health conditions. Operating under NCQA accreditation, the center provides structured clinical care across multiple levels — from medical detox through outpatient services — within a community-based, nonprofit model that distinguishes it from many private treatment options in the region.

The facility’s continuum of care begins with medical detox, making Harbor Care a direct option for people who need medically supervised withdrawal management before stepping into less intensive treatment. From there, clients can transition into a standard Outpatient Program or an Intensive Outpatient Program (IOP), allowing continued clinical support while living outside of a residential setting. This sequenced structure means patients do not have to change providers as their withdrawal stabilizes and they move into the recovery phase.

Clinical care at Harbor Care incorporates Cognitive Behavioral Therapy (CBT) and addresses trauma and PTSD alongside substance use — a recognition that co-occurring disorders frequently complicate withdrawal and long-term recovery. The dual diagnosis focus is built into the treatment model rather than treated as an add-on, which matters for individuals whose substance use is intertwined with underlying mental health conditions.

Harbor Care explicitly serves individuals who are Deaf or hard of hearing, a population that faces documented barriers accessing addiction treatment. The facility accepts a broad range of payment sources — including Medicaid, Medicare, TRICARE, private insurance, state insurance, self-pay, sliding scale fees, and financial assistance — reducing financial obstacles for people who might otherwise delay or forgo detox. Offices are open Monday through Friday, 8 a.m. to 5 p.m., and intake inquiries can be directed to (603) 821-7788.

Harbor Care offers medical detox as the entry point of its substance use treatment continuum at its Nashua location. For individuals whose physical dependence requires supervised withdrawal management, having detox services housed within the same nonprofit organization — rather than at a separate facility — allows for more coordinated transitions into the next level of care.

Following stabilization, clients can move directly into Harbor Care's Outpatient Program or Intensive Outpatient Program (IOP) without navigating a new intake process or losing clinical continuity. That integrated pathway is particularly relevant for people managing co-occurring disorders, where disruptions between care levels can undermine treatment gains made during detox.

Harbor Care treats co-occurring disorders and dual diagnosis conditions alongside substance use — including trauma and PTSD, which frequently co-exist with addiction and can complicate the withdrawal process if left unaddressed. The clinical team uses Cognitive Behavioral Therapy (CBT) as a core therapeutic method, a structured approach that targets the thought patterns and behaviors underlying both substance use and mental health symptoms.

Addressing these conditions in parallel, rather than sequentially, reflects an understanding that treating withdrawal without also engaging co-occurring psychiatric conditions often results in incomplete outcomes. Clients presenting with trauma histories or PTSD can expect those needs to be part of the clinical picture from the outset.

Harbor Care serves a broad adult population seeking detox and outpatient addiction treatment in Nashua, with a specific, documented commitment to serving individuals who are Deaf or hard of hearing — a group that frequently encounters access barriers in traditional treatment settings. Services are available in English.

On the financial side, the facility accepts Medicaid, Medicare, TRICARE, private insurance, state insurance, self-pay, sliding scale fees, and financial assistance. That range makes Harbor Care one of the more accessible detox and outpatient options in Hillsborough County for people across the income spectrum. To reach the intake team directly, call (603) 821-7788 or email ssgfoxintake@harborcarenh.org. The office is open Monday through Friday, 8 a.m. to 5 p.m.

Harbor Care holds accreditation from the National Committee for Quality Assurance (NCQA), a standards body focused on healthcare quality and care coordination. For individuals evaluating detox programs, NCQA accreditation signals that the organization meets defined clinical and operational benchmarks — a relevant data point when making a same-day or urgent care decision.

As a nonprofit, Harbor Care's broader organizational mission encompasses housing, healthcare, and veteran services across New Hampshire. The substance use treatment program at 45 High Street in Nashua operates within that mission, meaning the facility is oriented toward access and community impact rather than a purely commercial model. TRICARE acceptance also reflects a deliberate effort to serve veterans and active-duty military personnel seeking detox or outpatient treatment.
